2025-04-10ArmPkg: ArmFfaLib: Move ArmFfaLib implementation to MdeModulePkgKun Qin11-0/+1738
ArmFfaLib is an implementation of an industry specification-defined interface with UEFI specific method of handling Rx/Tx buffer sharing across multiple boot phases, which is more appropriately placed in MdeModulePkg. This update relocates the implementation of ArmFfaLib to MdeModulePkg, thereby supporting the FFA call primitives for all other packages that depend on this interface.

Adds a new library instance to support logging performance data in Standalone MM. - Add StandaloneMmPerformanceLib instance - Move common MM logic to a new file `SmmPerformanceLibInternal.c` - Since the library largely defers most logic to the performance measurement protocol a large degree of code can be shared between Standalone MM and Traditional MM.

2025-03-18MdeModulePkg: Move TdxMeasurementLib from UefiCpuPkgCeping Sun2-0/+117
There are 2 reasons to move TdxMeasurementLib LibraryClass from UefiCpuPkg to MdeModulePkg: 1. TpmMeasurementLib.h is located at MdeModulePkg/Include/Library. It is similiar as TdxMeasurementLib.h. 2. TdxMeasurementLib is designed for TDX Measurement, it can be called from SecurityPkg. And it is not much related to UefiCpuPkg. Based upon above consideration, it's better to move TdxMeasurementLib LibraryClass from UefiCpuPkg to MdeModulePkg.

The ESRT table is not required in UEFI firmware. In such cases, the table may not be present in the UEFI Configuration Table. The mEsrtTable is to check if the IsNestedFmpCapsule() function is invoked at runtime to determine whether to use gEsrtManagementProtocolGuid or the ESRT table from the Configuration Table. Unfortunately, the check does not cover situations where the ESRT is not present, potentially resulting in a kernel crash. This patch is intended to fix this issue.

2024-03-30MdeModulePkg: ImagePropertiesRecordLib: Use SectionAlignment for CodeSizeOliver Smith-Denny1-1/+3
When an ImageRecord is stored by ImagePropertiesRecordLib, it reports the CodeSegmentSize as the SizeOfRawData from the image. However, the image as loaded into memory is aligned to the SectionAlignment, so SizeOfRawData is under the actual size in memory. This is important, because the memory attributes table uses these image records to create its entries and it will report that the alignment of an image is incorrect, even though the actual image is correct. This was discovered on ARM64, which has a 64k runtime page granularity alignment, which is backed by a 64k section alignment for DXE_RUNTIME_DRIVERs. The runtime code and data was correctly being loaded into memory, however the memory attribute table was incorrectly reporting misaligned ranges to the OS, causing attributes to be ignored for these sections for OSes using greater than 4k pages. This patch correctly aligns the CodeSegmentSize to the SectionAlignment and the corresponding memory attribute table entries are now correctly aligned and pointing to the right places in memory.

Resolves a new CodeQL error due to the value being incremented in the loop being a narrower type than the variable it is being compared against. The variable is changed to a UINT32 type so it has the same width as the type it is being compared against. Issue explanation: In a loop condition, comparison of a value of a narrow type with a value of a wide type may result in unexpected behavior if the wider value is sufficiently large (or small). This is because the narrower value may overflow. This can lead to an infinite loop.

2023-12-19MdeModulePkg/UefiBootManagerLib: Signal ReadyToBoot on platform recoveryNeal Gompa1-0/+11
Currently, the ReadyToBoot event is only signaled when a formal Boot Manager option is executed (in BmBoot.c -> EfiBootManagerBoot ()). However, the introduction of Platform Recovery in UEFI 2.5 makes it necessary to signal ReadyToBoot when a Platform Recovery boot loader runs because otherwise it may lead to the execution of a boot loader that has similar requirements to a regular one that is not launched as a Boot Manager option. This is especially critical to ensuring that the graphical console is actually usable during platform recovery, as some platforms do rely on the ConsolePrefDxe driver, which only performs console initialization after ReadyToBoot is triggered. This patch fixes that behavior by calling EfiSignalEventReadyToBoot () in EfiBootManagerProcessLoadOption () when invoking platform recovery, which is the function that sets up the platform recovery boot process. The expected behavior has been clarified in the UEFI 2.10 specification to explicitly indicate this behavior is required for correct operation. This is a rebased version of the patch originally written by Pete Batard.

2023-11-27MdeModulePkg: Transition SMM MAT Logic to Use ImagePropertiesRecordLibTaylor Beebe1-0/+29
Now that the bugs are fixed in the MAT logic, we can remove the duplicate logic from PiSmmCore/MemoryAttributesTable.c and use ImagePropertiesRecordLib instead.

2023-11-27MdeModulePkg: Add NULL checks and Return Status to ImagePropertiesRecordLibTaylor Beebe1-123/+177
Update function headers to clarify the contract of each function and improve readability. Add NULL checks to all functions that take a pointer as an argument. Add return status to functions that may need to return early due to invalid input.

2023-11-27MdeModulePkg: Fix MAT SplitTable() LogicTaylor Beebe1-19/+19
SplitTable() does not properly handle the case where there is an odd number of code regions within a loaded image. When there are an odd number of code regions, at least one image region descriptor is overwritten with uninitialized memory which has caused crashes in the right conditions. This failure cases is documented extensively in the following bugzilla: https://bugzilla.tianocore.org/show_bug.cgi?id=4492 Cc: Jian J Wang <jian.j.wang@intel.com> Cc: Liming Gao <gaoliming@byosoft.com.cn> Cc: Dandan Bi <dandan.bi@intel.com> Signed-off-by: Taylor Beebe <taylor.d.beebe@gmail.com> Reviewed-by: Liming Gao <gaoliming@byosoft.com.cn>
2023-11-27MdeModulePkg: Fix MAT SplitRecord() LogicTaylor Beebe1-29/+27
SplitRecord() does not handle the case where a memory descriptor describes an image region plus extra pages before or after the image region. This patch fixes this case by carving off the unrelated regions into their own descriptors.
